Answer by Mimiwhatsup: The in photosynthesis will make the glucose that is used in cellular respiration to make ATP. Glucose is turned back into CO2(carbon dioxide), which is used in photosynthesis. While H2O(water) is broken down to form O2(oxygen) during photosynthesis, in cellular respiration O2(oxygen) is combined with hydrogen to form water.
(Down Below is their Equation)
Cellular Respiration: C6H12O6 + 6O2 → 6CO2 + 6H2O
Photosynthesis: 6CO2 + 6H2O → C6H12O6+ 6O2
